The parts of the grip mechanism are also arranged so that the cable cannot twist or become'entangled with I the jaws of the grip or the parts which operate the jaws in the event that the cable should become sud: denly slack.

As illustrated in the accompanying drawings the bogie truck to which the grip is applied comprises a body 1 which is mount- V ed upon wheels 2 in a suitable manner. The This invention relates to cable grips for cable which is adapted to draw the truck along the rails upon which the wheels travel I is'indicated at 3. Internally threaded col- An object of the .inventionis to provide a grip of simple and durable structure which is positive in its action in gripping.

gages the threads of the said collars and passes transversely through the same. .A handle lever 6 is mounted at the upper end ofthe screw shaft 5 above the upper surface of the body 1. The shaft 5 is provided in the vicinity of its lower end with an anpper face of the nut 8 is spaced from the shoulder 7 of the shaft 5 thereby providing an annular groove in the vicinity of the lower end of the said shaft. A spider 9 is provided with an opening which loosely receives that portion of the shaft 5 which lies between the shoulder 7 and the nut 8 and the said spider carries a: jaw 10. The jaw 10 is provided at its under. side with a strip of soft metalli, the said strip may be Babbitt metal or any other metal of a similarcharacter. The j aw 10 and strip 11 are positioned above the upper side of the cable3. A guide l2 depends from thelower side of the body 1 and lies at the side of the spider 9. The

1 said guide permits the. spider 9 to move vert1cally but restralns the same against turning movement with relation to the axis of the shaft5. 1

Eyes 13 are attached to the underside of 14 in the formof bell The arms 14: are provided at their lower inner ends with angularly disposed extensions 15 which carry a jaw 16 adapted to grip against the under sideofthe cable 3. The

The body 1 of the truck is provided at one side with a vertically disposed opening 19, having guide strips 20 positioned in the upper outer endof one of the; arms 14 is vicinity of the upper end thereof. A looking bar 21 is slidably mounted in the opening 19 and the said her is provided in the vicinity of itsupper end and atits gpp osite side with recesses 22 which slidably receive the inner edge portions of the guide strips 20. The upperend of the bar 21 projects above the upper surface of the body'l of the truck.

The bar 21 is provided at its lower with an angular ly disposed extremity 23 which liesunder a plate 24 attached to the under side of the body l. The extension 23 is provided at its lower edge with spaced recesses 25. The recesses are arranged-1n pairs-and between the members of eachpair a of recesses25 the bar 21 is provided with a downwardly disposed lug 26, the corners of which are'rounded or beveled as at 27. One set of recesses 25 1s adapted to recelve one of the arms 14 and the other set of recesses 25 is adapted to receivethe other arm 14 when the extension 23 is moved longitudinally underthe plate 24 inconse'quence ofthe' 'vices comprise plates 29 which' are secured to the-body 1 at the opposite ends of the guide strips 20 and tongues 30 are hingedly connected at their outer edges with the inner edges of the plates 29 and the inner edges of the said tongues lie against the opposite sides of-thebar 21 when the said tongues i a l 1 .v are swung down 1nto horizontal positions as shown in Fig. 1 of the drawing; 'When "-with the upper-side of the cable 3 "and thus either one ofthe tongues 30 is swung in an upward direction the bar 21 is free tobe 'moved in the opening 19 whereby one or the otherofthe recesses 25 of both' sets of recesse's may be brought vertically above-the at the inner ends of thearms may move down from the lower side of the cable 3 andrelease the same. VVhen the bar 21 is moved so thatthe lower'edges of-the lugs 26am vertically above the outer endsofthearms 1 4 the outer ends of-the said arms are held in depressed positions whereby the inner cable 3. Theends of the lugs 26 are rounded as at 27 inorder to permitthe said lugs to move readily over the of the arms 14.

are vertically above the outer end L portions 9 of the arms 14 and in contact with the same.

i The screw shaft '5 is turned in the collars 4 whereby the'jaw 10 is 'held down' firin toouter end portions 1 outer ends of the arms 14 and thus the said arms may swing whereby thefjaw16 carried ward the-MPPQlfiSldGyQf the cable 3. In the event that it is desired to quickly release the r -twin th cabl an t per ta sai si one or the other of the tongues' 30 in an upward direction thereby releasing the 21. The bar ie-then moved along the'opening 19 whereby one or the other of the recesses 25 ,ofboth sets of recesses are brought vertically abiive the outer end portions of the arms 14 thus permittingithe outer ends of the said arms to swing vertically under the weight of the cable 13. -As theysaid armssw'ing'as indicated their lower ends .1 are moved in a downwarddirection and thejaw 16 is moved away from the cable 3- fora suflicient distance to permit the cable to move longitudinally between the-jaws 16 land lO -withoutmoving the-bogie' truck; When it is desiredto apply the jaws of thergrip to the cable 8 the screw shaft 5 is first moved in an upward direction by turning the same in the collars 4 whereby the jaw 10 is elevated. The bar "21is thenmoved along the opening 19 so that the lower ed'g'es of: the lugs '26 are-positionedtdirectly above the outer=end portions of the arms 14andincontactwiththe same.

The tongues 30 are then swung-totheir lowermost positions whereby the bar *2liisheld -againstmove1nent'inthe opening 19.

grip the cable when the deviceisproperly "manipulated. Also when the cable releasedby the aws the said jaws are-in such position aboutthe cable that the event thatthe cable becomes suddenly slackit can not wind or= twist about the screw shaft 5 and cause damage.

From the foregoing description taken in conjunction with the accompanying drawmg itwill be seenthat gripping mechanism of simple aild durable structure is proyided and that the samemay be easily and -When the cable 3 is-gripped-betweenthe jaws 10 and-16 the; lower edgesjof the lugs 26 slack.

Having described the invention what is claimed is 1. In combination with a cable and a truck mounted for movement, a cable grip comprising a jaw located at the side of the cable, a screw shaft mounted upon the truck and connected with said jaw for raising and lowering the same, arms pivoted upon the truck, a jaw carried by said arms and lying at the opposite side of the cable from the first mentioned jaw, and a bar movably mounted upon the truck and adapted to engage the arms to hold the jaw carried thereby in gripping position against the cable.

2. I11 combination with a cable and a truck mounted for movement, a gripping mechanism comprising a jaw movably mounted upon the truck, means for guiding the .movement of said jaw, a. screw shaft threaded upon the truck and voperatively connectedwith said jaw, arms pivoted upon the truck and carrying a jaw which lies at the side of the cable, a bar movably mounted upon the truck and having an extension provided with notches and intervening lugs adapted to engage the said arms and means mounted upon the truck for temporarily holding the bar against movement.

3. In combination with a cable and a truck mounted for movement, a gripping mechanism comprising a jaw, a shaft screwthreaded upon the truck and operatively connected with said jaw, arms pivoted upon the truck, a jaw carried by the said arms and lying at the side of the cable, a bar connecting said arms together, a bar movably mounted up on the truck and provided with an angularly disposed eXtension having spaced recesses with lugs positioned between the said recesses, the said lugs adapted to engage the arms and hold the jaw mounted upon the arms in contact with the cable and means mounted upon the truck for temporarily holding the bar which is movably mounted upon the truck against movement.

4:. In combination with a cable and a truck mounted for movement a gripping device comprising a jaw, means mounted upon the truck for raising and lowering said jaw, arms pivoted upon the truck, a jaw carried by the arms and lying at the side of the cable, a. bar movably mounted upon the truck and having notches with intervening lugs adapted to engage the arms to hold the jaw carried thereby in engagement with the cable, and tongues pivotally mounted upon the truck and lying at the opposite sides of the said bar and adapted to temporarily hold the said bar against movement.
